USAutomatic PATRIOT I - Sensitivity Adjustments and Entrapment Alarm

Current Sense Adjustments and Entrapment Alarm
The current sense adjustment feature designed into
the control board allows you to adjust the amount of
pressure the gate will apply to an object before the
gate is stopped and reversed by the control board.
The Patriot control board has 2 current sense
adjustment dials located in the upper left corner of
the control board. These adjustments control the
amount of current the control board will allow the
motor to draw from the battery to operate your gate.
Maximum sensitivity is the least amount of current
(or force) allowed.
We intentionally set the sensors at a medium sensitivity setting. This may need to be adjusted to
achieve gate movement of larger gates without tripping the sensitivity circuit and causing the gate to
reverse direction. If the gate reverses direction twice and then stops, the control board will need to be
reset.
A typical adjustment setting is between 4 to 7 on the adjustment dial. A setting of 8 or more may be
required on very large gates. If a setting above 8 is required for proper operation without just cause,
you should check the gate, gate hinges or linear actuator for possible problems.
Testing the Sensitivity feature:
Sensitivity feature is inactive for the rst second of gate operation.
While the gate is operating (open or closed direction) apply force to the gate until it stops and
reverses. If traveling in the open direction the gate should reverse about 1 foot, if traveling in the
closed direction the gate will reverse to the fully open position.
Entrapment alarm:
The entrapment alarm is installed to give an audible alert whenever the gate sensitivity feature is
activated twice during an open or close cycle.
For example, the gate is closing and is stopped by some object, it will then reverse direction. If the
gate encounters a second object before reaching the fully open position it will stop again and enter a
hard shutdown, which will set off the entrapment alarm. The alarm will sound for 5 minutes or until the
reset button on the control board is pressed and released. The hard shutdown will require the reset
button to be pressed to place the gate operator back into operation.
